RTM-E Digital Cable Tension Meter

The RTM-D is a cable tension meter especially developed for the determination of (high) tension in cables like guy wires, support cables, architectural cables etc. The RTM-D can be placed directly on the cable. The device will show the tension on the display.

The RTM-D is suitable for measurements up to 30.000 KG and cable diameters up to 38 mm. The measured values are directly shown on the display without use of a reference table.

Measuring principle:
The RTM-D is placed on the cable under a pre-defined angle. This angle is then used to determine the tension in the cable. Since the gauge is calibrated to the cable that is measured it will directly show the tension value. These calibrations can be saved inside the gauge and it is possible to save up to 10 different cable calibrations. Values can be displayed in N, Lbs or Metric Tons

The RTM-D determines quickly, safely, accurately and conveniently cable tension. It can withstand force two times its rated capacity without damage. The RTM features hardened steel cable guides which ensures trouble free operation in the toughest outdoor environments.

Before the RTM-20E can be ordered, we first need to check if the cables you are going to test are available for calibration at the factory. Please download the link.


and send the completed form to us by email. We can then check if your cables are available or if we require 12 meter samples for calibration.
